AgI Silica Core Shell Nanoparticles (Silver Iodide Silica, 99.9%, APS: 80-100nm, Metal Salt Core)

AgI Silica Core-Shell Nanoparticles

AgI siIica core-shell nanoparticles combine the unique properties of silver iodide (AgI) and silica (SiO₂), resulting in a versatile material with applications across a wide range of fields.

Photothermal and Photodynamic Therapy

Cancer Treatment: The photocatalytic and photothermal properties of the AgI core enable AgI/SiO₂ nanoparticles to be used in photothermal therapy for cancer treatment. When exposed to near-infrared light, these nanoparticles can generate heat to destroy tumor cells while minimizing damage to surrounding healthy tissue.

Photodynamic Therapy: The AgI core can also generate reactive oxygen species (ROS) upon light exposure, which can be used in photodynamic therapy (PDT) to treat cancer or infections. The silica shell helps protect the AgI core and improves the stability of the nanoparticles during treatment.

6. Optical and Photonic Applications

Surface-Enhanced Raman Spectroscopy (SERS): The AgI core can enhance Raman signals, making AgI/SiO₂ nanoparticles ideal for SERS applications. This allows for the highly sensitive detection of molecular species, useful in chemical analysis, forensic investigations, and medical diagnostics.

Optical Sensing: The combination of AgI’s optical properties and the silica shell’s tunability allows for the development of optical sensors that can detect changes in the surrounding environment, such as pH, temperature, or the presence of specific analytes.

Catalysis

Photocatalytic Reactions: AgI is known for its ability to catalyze oxidation reactions under light, making AgI/SiO₂ nanoparticles useful in green chemistry for sustainable production processes. The SiO₂ shell enhances the stability and reusability of the nanoparticles, making them effective in long-term catalytic applications, such as CO oxidation and water splitting.

Food and Agriculture

Food Preservation: Due to its antimicrobial properties, AgI/SiO₂ nanoparticles can be incorporated into food packaging materials to prevent microbial growth and extend shelf life. They can also be used in agricultural applications to protect crops from bacterial or fungal infections.

Pesticide Delivery: The nanoparticles can be used as carriers for controlled release of pesticides, delivering them to targeted areas while minimizing environmental contamination.
